THANK YOU. EXACTLY! Yet they make it into a pilgrimage to Uman.
What I meant, which it seems you did not understand, is that Rosh Hashanah does not require the Jew to come to Israel as do the Regalim (Passover, Shavuot, Sukkot). Thus, aside from the question of whether a Jew currently living in Eretz Yisrael should (or should not) be able to leave in order to attend the Uman festival. So I do not see a problem if a Jew currently in Galut goes to this event.
For me the attraction is the feeling of Unity which is felt in such a large gathering of like-minded people. Having attended large 'rock-music' events where the entire crowd appeared to have such unity was an awesome experience. It is truly a spiritual experience to have so many people who are so very motivated to make Teshuva, to visit the kever of Rabbi Nachman, and to daven with a special intensity.
So I leave it to a question of whether Jews currently in Israel should leave. There is disagreement on this issue.
